Thisinvention relates Ito iextensibleasidelsup- "portsforslidingdrawers;shutters, doors'aiid' the like, in cases whereiiit iside'si'rible toobtain a horizontal movement of -ne,part relatively to another part.

The invention will be described with particular reference to a slidingdrawer, which term is designed to include sliding trays and shelves,hereinafter generically referred to as drawers, where the weight of thedrawer and its contents is sustained in a horizontal position when thedrawer is pulled out of the cabinet or like part, and it has for itsobject to simplify the operative parts and to reduce the depth of thecabinet without reducing the depth of the drawer, and to this endaccording to this invention the supporting means comprises a pair ofrunners or channels the back ends of which are bent upwardly at rightangles to the main part thereof, a pair of arms pivoted to the sides ofthe drawer, rollers on the free ends of said arms slidably arranged inor on. such runners or channels, and means fixed adjacent the back endof the drawer with which said arms make contact when said drawerapproaches its mid-outward position and by means of which the drawer issustained in a horizontal position.

In the accompanying drawings which illustrate this invention:

Figure 1 is a side elevation, partly in section, of one embodiment ofthe invention.

Figure 2 is a front elevation, partly in section, on line II-II ofFigure 1.

The supporting means for the drawer I comprises a pair of runners orchannels 2 the back ends of which are bent upwardly at right angles tothe main part thereof. The runners or channels 2 are of shallow U-shapeform in cross-section and are secured to the inner walls 3 of thecabinet with the channels facing towards each other. The drawer I issupported at; its forward end on a pair of rollers I mounted on pins 5secured to the walls 3 of the cabinet while the rear end is supported bya pair of rollers 6 rotatably mounted on the drawer I in such a positionthat the rollers run in the respective channels 2 except when the drawerI is pulled out to its fullest extent. Each of the pins 1 carryingtherollers 6 is arranged to support one end of an arm 8 furnished at itsfree end with a further roller 9 arranged to run in the adjacentchannels. The rear end of the drawer I is provided on each side with afixed stop I0. Extensions I4 on the free ends of arms 8 serve to mountrollers I3.

The arrangement of the device is such that when the drawer I is in itsclosed or inward posi- "tionjsaid draweris supported in a horizontal-pos'ition,at*the front by'the two'rollers 4'located atthe-front'ofthecabinet and bythe rollers 6 running" in the channels 2 as shown bybroken linesin Figure 1. The rollers 9 on thefre e ends of-the'arms 8are located adj acent the upper ends "of the upwardly extending ends of"the channels 2. the drawer I is "drawn outwardly the rollers 9 run downthe upwardly extending channels 2 until they enter the horizontalportion thereof and simultaneously the upper edges of the arms 8 comeinto contact with the under surface of the stops Ill on the drawer andany tilting of the drawer is prevented. The rollers I3 serve to guidethe rollers 9 from the vertical to the horizontal portions of thechannels 2 and vice versa.

What I claim is:

1. In a cabinet having opposite side walls and a drawer opening leadingfrom the front rearwardly into the cabinet between the side walls, thecombination, with a drawer adapted to extend slidably through saiddrawer opening into the cabinet, of means for supporting the drawer,including a pair of rollers mounted within the cabinet upon the interiorof the side walls at the front end of the drawer opening therein forsupporting the drawer from beneath; a pair of opposite channel-shapedsupporting runners secured to the interior of said side walls withinsaid cabinet with the open sides of the channelshaped runners openinginwardly and mutually facing each other, each runner comprising ahorizontal portion extending lengthwise of said drawer and a verticalportion extending rigidly upward from the rear end of said horizontalportion with a curved portion disposed between and integrallyinterconnecting the horizontal and vertical portions; a pair of pinsmounted on the opposite sides of said drawer adjacent to the rear endthereof; a pair of rollers rotatably mounted on said pins for engagementin the horizontal portions of said runners; a pair of arms pivotallymounted intermediate the ends thereof on the pins; a second pair ofrollers mounted on the rear ends of the arms in effective positions toride exteriorly upon the runners for guiding the first pair of rollersfrom within the horizontal portion of said runners toward the verticalportion thereof; a third pair of rollers also mounted on the rear endsof said arms to ride within said portions of said runners and retain thesecond pair of rollers in operative rolling contact with the exterior ofsaid portions of said runners; a pair of stop elements disposed onopposite sides of said drawer adjacent to the rear ends thereof, thefront ends of said arms engaging beneath said stop elements to supportsaid drawer when the latter is pulled out so as to extend outwardly fromsaid cabinet.

2. In a cabinet having opposite side walls and a drawer opening leadingfrom the front'rearwardly into the cabinet between the side walls,

the combination, with a drawer adapted to ex- M tend slidably throughsaid drawer opening into the cabinet, of means for supporting thedrawer,

including a pair of rollers mounted within the cabinet upon the interiorof the side walls at the front end of the drawer opening therein forsupporting the drawer from beneath; a pair ofopposite channel-shapedsupporting runners secured to the interior of said side walls withinsaid cabinet with the open sides of the channelshaped runners openinginwardly andmutually from said cabinet.

tions of said runners; a pair of arms pivotally mounted intermediate theends thereof on the pins; a second pair of rollers mounted on the rearends of the arms in effective positions to ride exteriorly upon therunners for guiding the jfiijst paiisgo'f rollers fro'infwithih oneportion of said runners toward another portion; and a pair of stopelements disposed on opposite sides of said drawer adjacent tothe rearends thereof. the front ends of said arms engaging beneath saidstopfelements to support said drawer when the latter is pulled out so asto extend outwardly I HAROLD SHAND. i REFERENCES CITED i'ilheflfollowingreferences are of record in the facing each other, each runnercomprising a horizontal portion extending lengthwise of said file ofthis patent:
